Automobile Fuel Economy Test Methods And Appreciation System

It goes without saying that the urban transportation brings forth the urban economy and social development,improves people's mobility.But there exist some negative effects while we should pay close attention to.These negative effects include energy consumption,environment polluting,traffic accidents increasing,etc.So the urban transportation development concerns is not whether or not we should foster the vehicle transportation development,but how to develop it,how to regulate the development while restricting its disadvantages in reasonable scope.Whether from energy security or the control of greenhouse gas emissions and promote the use of new technology,and other point of view,the development of the fuel consumption evaluation system,corresponding with the Chinese road conditions and the domestic car technology,will be very necessary and urgent.For this purpose,through the car's fuel consumption in the domestic survey analysis,multi-angle shows the car's fuel consumption in the domestic distribution.To make users more intuitive understanding of the fuel consumption of energy-saving vehicles situation,basing on two comprehensive evaluation of fuel consumption indicators,the classification of the vehicle's fuel economy and grading of the corresponding assessment stars(on the C-ncap Star inspired),a popularization of this approach will allow users more intuitive understanding of energy-saving vehicles.In addition,make a more comprehensive analysis and experimental on factors,impacting vehicle fuel consumption,especially the impact of air conditioning on fuel consumption,the United States through the emerging standards for air-conditioning SCO3 opening under the heat load simulation experiments,compared Open air-conditioning with air-conditioning shut down under different traffic condition of fuel consumption,described the impact of air conditioning on fuel consumption.Vehicle fuel consumption is a systematic and complicated aspect in the urban transportation system.Some of it attributes to the characters of vehicle,others relates to the road and traffic condition,still others seem to stress the evaluation methods of it.Firstly, describe fuel economy standards and the corresponding test and running cycle,make corresponding comparison.Made evaluation of various indicators of the relationship.On the basis of this analysis of the impact of vehicle fuel consumption factors and measurement method,according to China Automotive Technology and Research Center on the light truck emissions test results.In accordance with the principles of the projected vehicle fuel consumption and statistical analysis of the situation,the proposed vehicle fuel economic performance evaluation method,and accordingly the vehicle is divided into four grades.Finally,the Tianjin running cycle extracted,and the fuel consumption of Tianjin tested in drum bed,and contrasted with the road test.
